CHARLES F. KELLOM, OF DELAIR, NEIV JERSEY.

GREASE-CUP OR LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 645.227, dated March 13, 1900. Application filed May 13, 1899. Serial No. 716,626. (No model.)

To all whom it may concern..-

a citizen of the United States, residing at Delair, in the county of Camden, State of New Jersey, have invented a new and useful Improvement in Grease-Cups or Lubricators, whichimprovementis fully setforth in the following specification and accompanying drawings.

My invention consists of a grease-cup or lubricator in which provision is made in a simple and effective manner for agitating or breaking up the lubricant to prevent coagulation or hardening thereof, which sometimes occurs, and also for raising the temperature thereof sufficiently to insure ,a satisfactory feed thereof.

It furtherconsists of novel details of construction, all as will be hereinafter fullyset forth, and particularly pointed out in the claims.

Thelubr'icator can be applied to shaft hangers and bearings of various kinds, and for the purpose of illustration I have shown a wellknown form of shaft-han ger and will-now particularly describe the same.

Figure 1 represents a perspective view of a lubricating device embodying my invention and a portion of a shaft and hanger to which the same is applicable. Fig. 2 represents, on an enlarged scale, a section on line a; m, Fig. 1.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates the lubricating device, the same consisting of a cup B, having its lower portion 0 screwthreaded to engage the threaded seat or socket D, the latter being provided with a base E and dependingwalls F, that rest upon the bearing G, in which latter is the shaft H. The bearing has an opening J, in which the lower portion K of the cup B is seated, said portion K having the opening L therein, which communicates with the passage M, leading to the shaft H.

N designates a rotatable cap mounted upon the upper portion of the cup B, said cap having an opening P at or near the center thereof and another opening Q near its outer edge.

R designates the agitator, which consists of a stem. U and finger T, joined by a top member S. The stem U is helical or spiral in shape and preferably composed of copper or similar material and extends to and rests upon the rotatable shaft H, while the finger T enters the opening Q and is located in proximity to the inner side of the cup B and in the present instance consists of a flat thin strip of material, as will be evident from Fig. 2.

' The device is held in position upon the cylinder or bearing by any suitable means, in the present instance by the strip or wire V, whose ends engage the walls F.

The operation is as follows: The parts normally appear when assembled as indicated in Figs. 1 and 2, the cup 13 being supplied with the lubricant. If for any reason the'1ubri cant becomes hardened or coagulated, which sometimes occurs at different points near the cup B, it is only necessary for the attendant to turn or rotate the cap N, whereby it will be seen that the'finger T sweeps around the inner face of the cup B, and thus scraping the lubricant from said face, so that it passes to the center of the cup, where it is again acted on by the stem, said stem when turned also serving as an anger to screw or force down the lubricant, thus more effectively feeding it to the place of service, said stem also producing a passage whereby the lubricant can readily flow through thecup, assisted by the heating of said stem, due to its frictional contact with the shaft.

The base E, with the walls F, adapts the lubricator to be nicely seated onthe bearing G. The bottom of the cup is conical, so that it will nicely fit the opening in the bearing and adapt itself to openings of different diameters or depths.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a lubricator, a cup having a freely-rotatable cap, and a finger situated within said cup and near one side thereof, said cap and fingerbeing suitably connected, whereby the latter can be rotated by the former.

2. In a lubricator, a cup having a freely-rotatable cap, and an agitator situated within said cup, said cap and agitator being suitably connected, whereby the latter can be rotated by the former.

3. In a lubricator, a cup having a freely-rotatable cap, and a stem and a finger situated a stem passing freely through said central,

. opening and resting at its lower end upon the rotatable part to'be lubricated, and a finger connected with said stem and passing freely through said side'opening.

6. In a lubricating device, a cup threaded at its lower portion and provided with a base portion having an opening therethrough, a socket provided With projecting Walls and fasteningdeviees for the reception of said cup, a rotatable cap mounted on said cup and having openings therein, and an agitator mounted in said openings and adapted to be moved in unison with said cap, said agitator having depending iimbs within said cup of different lengths, the inner limb being helical or spiral and the other or outer limb being located in proximity to the interior of said casing.
